At Tommy Nordbergh Maskin & Transport AB they are sure that “RUBBLE MASTER manufactures best equipment and provides the best service.” That is why the Swedish company has opted for a new RM impact crusher to replace their RM 80GO!. Since the RM 80GO! began operating in Sweden in 2012 Nordberghs’ business has developed well. Increasingly large amounts of asphalt, concrete and natural rock are being produced and are now being processed by the biggest RM impact crusher, the RM 120GO!. To minimise downtimes the company has also chosen several extremely useful optional extras: an RM crusher works with the RM MS125GO!, a mesh deck screen and a hydraulically pivoting refeeding belt, which give customers great flexibility in daily operation. The machine crushes and screens in a single pass: the RM MS125GO! guarantees precise screening of material from 0/10 to 0/65.

The hydraulically pivoting refeeding belt transports oversize grain either to the stockpile or back to the crusher in a closed circuit. With the aid of a handling frame, the screen is fitted to the machine in less than 15 minutes, and the RM screen tensioner allows rapid changing of the screens when other grain sizes are required. Owing to the frequent changes between types of feed material, the hydraulic hammer changing system is also a worthwhile option for Nordberghs. 40% of the material crushed by the RM 120GO! is concrete and 40% is asphalt, while natural rock accounts for the remaining 20%. Since recycling asphalt and concrete is their main focus, Nordberghs chose an optional even more wear-resistant crusher lining and a steep conveyor belt. The steep conveyor belt improves the separation of steel from the feed material and the lower wear extends the service life of the belt.

Best Service and Smart Maintenance
Nordberghs’ vision and business concept are very similar to those of RM: “The aim is always to be first choice when orders are placed and always to exceed customers’ expectations with dedicated employees.” In Sweden this is done for RUBBLE MASTER by the RM sales partner OP System. Nordberghs is also highly satisfied with the service provided. Additionally, the company has opted for a form of digital support: RM GO! SMART makes analysis, maintenance and spare parts management even easier. This intuitive tool provides live data at any time on the machine’s status, daily reports and, in the event of problems, instructions on remedying the fault direct to a smartphone or tablet. However, problems are hardly to be expected, especially with the generator, since the encapsulated generator is tougher than ever and dust-resistant, making it ideal for use in asphalt.

Tommy Nordbergh Maskin & Transport AB
The Swedish firm of Tommy Nordbergh Maskin & Transport AB was founded in 1963 in Hjärnarp, southern Sweden.

Crushing at a high output and low wear, and that in every possible and impossible location, is not an issue for RM crushers. They manage to generate the highest quality value grain from natural stone on site. Depending on the desired combination of machinery. The end result is always cubic aggregate.

Quartz gravel, granite and riverbed gravel are not easy to process because high levels of quartz cause high wear. However, RM crushers are designed for such materials: thanks to their compact size they can achieve high throughputs even in tight spaces, producing valuable aggregate directly on site at all times.

Processing 24,000 tons of gravel with a quartz content of around 90 percent to produce 0-32 mm value grain
– that was the right challenge for the RM 100GO!. The mobile power pack with its wear-resistant hammers rose to this challenge in the Vienna basin extremely economically. Excavator and loader drivers are impressed.

Building roads to connect to eastern Mexico was difficult because of the problematic terrain. It was necessary to prepare materials on site because of the remote locations of the construction sites. The RM 70GO! is ideal for challenges like this. Its manoeuvrability make it a perfect machine.

The Swiss company Mühlebach AG has been successfully processing gravel for 40 years. As pioneers in this business field, they demand machines that are state of the art. They have now added an RM V550GO! to their fleet of machines in order to meet the demand for crushed sand and grit.

At the beginning of the year the RM V550GO! made light work of transforming 0-200 mm river rock into fine 0-19 mm value grain. The awesome capacity and low diesel consumption were key in the Argentine company’s decision to purchase the RM V550GO!.
